上述した種類のコネクタでは、一般に、シールドシェルとハウジングとの間にパッキン等のシール部材を配置する場合、長期安定的にシール性を高めるべく、シールドシェルとハウジングとの相対移動を出来る限り抑制するようになっている。シール部材の面圧の変動を避けるためである。あるいは、シール部材自体を設けず、シールドシェルとハウジングとを密着させるようになっている。ところが、このように各部品の変位を過度に規制しようとすると、シールドシェルやハウジングの製造公差や、相手側コネクタの製造公差が原因で、コネクタ同士の嵌合を適正に行うことができなくなる可能性がある。 In the above-mentioned type of connector, when a sealing member such as packing is placed between the shield shell and the housing, relative movement between the shield shell and the housing is generally suppressed as much as possible in order to stably improve the sealing performance for a long period of time. It's like This is to avoid fluctuations in the surface pressure of the sealing member. Alternatively, the seal member itself is not provided, and the shield shell and the housing are brought into close contact with each other. However, if you try to restrict the displacement of each part excessively in this way, the connectors may not be properly mated due to the manufacturing tolerance of the shield shell and housing, and the manufacturing tolerance of the mating connector. have a nature.

＜実施形態＞
以下、図面を参照しながら、本発明の実施形態に係るコネクタ１について説明する。図１に示すコネクタ１は、コネクタ１が有する一対の電線２０と、コネクタ１に嵌合される相手側コネクタ（図示省略）と、を電気的に接続する中継コネクタとして機能する。 <Embodiment>
A connector 1 according to an embodiment of the present invention will be described below with reference to the drawings. The connector 1 shown in FIG. 1 functions as a relay connector that electrically connects a pair of electric wires 20 included in the connector 1 and a mating connector (not shown) fitted to the connector 1 .

以下、説明の便宜上、図１～図３に示すように、「前後方向」、「上下方向」及び「幅方向」を定義する。「前後方向」、「上下方向」及び「幅方向」は、互いに直交している。前後方向は、コネクタ１と相手側コネクタとの嵌合方向と一致しており、「前」及び「後」はそれぞれ、コネクタ１における相手側コネクタとの嵌合の進行側及び退行側に対応している。 Hereinafter, for convenience of explanation, "front-rear direction", "vertical direction" and "width direction" are defined as shown in FIGS. The "longitudinal direction", the "vertical direction" and the "width direction" are orthogonal to each other. The front-rear direction corresponds to the mating direction of the connector 1 and the mating connector, and "front" and "rear" respectively correspond to the advancing side and the retreating side of mating of the connector 1 with the mating connector. ing.

図１及び図２に示すように、コネクタ１は、一対の端子金具１０と、一対の端子金具１０に繋がる一対の電線２０と、一対の端子金具１０を収容するハウジング３０と、ハウジング３０に後側から装着されるシールドシェル４０と、ハウジング３０及びシールドシェルの間に挟まれるシール部材５０と、シールドシェル４０及び一対の電線２０を覆うブーツ６０と、ハウジング３０に前側から装着されるパッキン７０と、を備える。以下、コネクタ１を構成する各部材について順に説明する。 As shown in FIGS. 1 and 2, the connector 1 includes a pair of terminal fittings 10, a pair of electric wires 20 connected to the pair of terminal fittings 10, a housing 30 that accommodates the pair of terminal fittings 10, and a rear portion of the housing 30. A shield shell 40 attached from the side, a seal member 50 sandwiched between the housing 30 and the shield shell, a boot 60 covering the shield shell 40 and the pair of electric wires 20, and a packing 70 attached to the housing 30 from the front side. , provided. Each member constituting the connector 1 will be described in order below.

まず、端子金具１０及び電線２０について説明する。端子金具１０は、金属板に対してプレス加工及び曲げ加工等を施すことで形成されており、前後方向に延びる形状を有している。端子金具１０は、前後方向に延びる細長い平板状の端子部１１（図１参照）と、端子部１１の後端部に位置する接続部（図示省略）と、を一体に有する。端子金具１０の接続部には、電線２０の端部が接続される。 First, the terminal fitting 10 and the electric wire 20 will be described. The terminal fitting 10 is formed by subjecting a metal plate to press work, bending work, or the like, and has a shape extending in the front-rear direction. The terminal fitting 10 integrally has an elongated plate-like terminal portion 11 (see FIG. 1) extending in the front-rear direction and a connection portion (not shown) located at the rear end portion of the terminal portion 11 . An end portion of the electric wire 20 is connected to the connection portion of the terminal fitting 10 .

電線２０は、金属製の導体芯線と、導体芯線を覆う絶縁被覆とで構成されている。電線２０の端部では、絶縁被覆が除去されて導体芯線が露出しており、露出した導体芯線に端子金具１０の接続部が加締め固定されている。これにより、端子金具１０に繋がる電線２０が、端子金具１０の接続部から後方に延出している。 The electric wire 20 is composed of a metallic conductor core wire and an insulating coating covering the conductor core wire. At the end of the electric wire 20, the insulation coating is removed to expose the conductor core wire, and the connection portion of the terminal fitting 10 is crimped and fixed to the exposed conductor core wire. As a result, the electric wire 20 connected to the terminal fitting 10 extends rearward from the connection portion of the terminal fitting 10 .

次いで、ハウジング３０について説明する。ハウジング３０は、樹脂成形品である。ハウジング３０は、図１及び図２に示すように、前後方向に延びる筒状の形状を有しており、前後方向からみて幅方向に長い扁平な形状を有している。ハウジング３０の前後方向中央部の外周には、全周に亘って径方向外側に突出するフランジ部３１が形成されている。ハウジング３０におけるフランジ部３１より前側の部分が、相手側コネクタの筒状の相手側嵌合部（図示省略）に内挿されて嵌合する嵌合部３２を構成し、ハウジング３０におけるフランジ部３１より後側の部分が、シールドシェル４０に内挿される挿入部３３を構成している（図２参照）。挿入部３３におけるフランジ部３１との境界部分には、径方向内側に窪む環状溝部３４が形成されている（図２参照）。 Next, the housing 30 will be explained. The housing 30 is a molded resin product. As shown in FIGS. 1 and 2, the housing 30 has a tubular shape extending in the front-rear direction, and has a flat shape elongated in the width direction when viewed from the front-rear direction. A flange portion 31 that protrudes radially outward over the entire circumference is formed on the outer periphery of the housing 30 at the central portion in the front-rear direction. A portion of the housing 30 on the front side of the flange portion 31 constitutes a fitting portion 32 that is inserted and fitted into a cylindrical mating fitting portion (not shown) of the mating connector. A more rear portion constitutes an insertion portion 33 that is inserted into the shield shell 40 (see FIG. 2). An annular groove 34 that is recessed radially inward is formed at the boundary between the insertion portion 33 and the flange portion 31 (see FIG. 2).

ハウジング３０の内部には、幅方向に間隔を空けて並ぶ一対の箇所の各々にて、前側から後側に向けて、端子挿通孔３５（図１参照）及び端子収容室（図示省略）が、この順に、且つ、互いに前後方向に連通するように、形成されている。端子挿通孔３５の前端は、ハウジング３０の前端（嵌合部３２の前端）に開口し、端子収容室の後端は、ハウジング３０の後端（挿入部３３の後端）に開口している。 Inside the housing 30, terminal insertion holes 35 (see FIG. 1) and terminal receiving chambers (not shown) are formed in each of a pair of locations spaced apart in the width direction from the front side to the rear side. They are formed in this order and communicate with each other in the front-rear direction. The front end of the terminal insertion hole 35 opens to the front end of the housing 30 (the front end of the fitting portion 32), and the rear end of the terminal receiving chamber opens to the rear end of the housing 30 (the rear end of the insertion portion 33). .

一対の電線２０の端部が接続された一対の端子金具１０は、ハウジング３０に収容させる。このため、各端子金具１０が、ハウジング３０の内部に後側から挿入される。これにより、各端子部１１が対応する端子挿通孔３５に挿通され、且つ、各接続部が対応する端子収容室に収容される。端子金具１０の挿入完了状態では、一対の端子部１１の前方部分が、ハウジング３０の前端（嵌合部３２の前端）から前方へ突出し（図１参照）、且つ、一対の端子金具１０から後方に延出する一対の電線２０が、ハウジング３０の後端（挿入部３３の後端）から後方へ延出している（図１参照）。なお、必要に応じて、電線２０の外周面と端子収容室の内周面との間に挟持されて両者間の環状隙間を封止するパッキンや、前記パッキンの後方への脱落を防止するホルダ等が設けられても良い。 A pair of terminal fittings 10 to which the ends of a pair of electric wires 20 are connected are housed in a housing 30 . Therefore, each terminal fitting 10 is inserted into the housing 30 from the rear side. As a result, each terminal portion 11 is inserted into the corresponding terminal insertion hole 35 and each connection portion is accommodated in the corresponding terminal accommodating chamber. When the terminal fittings 10 are completely inserted, the front portions of the pair of terminal portions 11 protrude forward from the front end of the housing 30 (the front end of the fitting portion 32) (see FIG. 1) and extend rearward from the pair of terminal fittings 10. A pair of electric wires 20 extend rearward from the rear end of the housing 30 (the rear end of the insertion portion 33) (see FIG. 1). In addition, if necessary, packing may be sandwiched between the outer peripheral surface of the wire 20 and the inner peripheral surface of the terminal accommodating chamber to seal the annular gap therebetween, or a holder may be provided to prevent the packing from falling off backward. etc. may be provided.

次いで、シールドシェル４０及びシール部材５０について説明する。金属製のシールドシェル４０は、図１及び図２に示すように、ハウジング３０の挿入部３３に外挿可能な前後方向に延びる筒状の形状を有している。シールドシェル４０は、ハウジング３０の挿入部３３に後側から装着されて、ハウジング３０内部に位置する一対の電線２０への電磁ノイズの伝達を防止する機能を果たす。 Next, the shield shell 40 and the seal member 50 will be explained. As shown in FIGS. 1 and 2 , the metal shield shell 40 has a tubular shape extending in the front-rear direction and can be inserted into the insertion portion 33 of the housing 30 . The shield shell 40 is attached to the insertion portion 33 of the housing 30 from the rear side and functions to prevent transmission of electromagnetic noise to the pair of electric wires 20 located inside the housing 30 .

シール部材５０は、ハウジング３０の挿入部３３と、挿入部３３に外挿されるシールドシェル４０との間の環状隙間を封止する機能を果たす部材である。ゴム製のシール部材５０は、図２及び図３に示すように、前後方向に延びる筒状の本体部５１と、本体部５１の前端から径方向内側に突出する環状の突部５２と、を備える。本体部５１の外周面には、径方向外側に突出し且つ前後方向に間隔を空けて並ぶ複数の環状リップ５１ａが形成され、本体部５１の内周面にも、径方向内側に突出し且つ前後方向に間隔を空けて並ぶ複数の環状リップ５１ｂが形成されている。 The sealing member 50 is a member that functions to seal an annular gap between the insertion portion 33 of the housing 30 and the shield shell 40 that is externally inserted into the insertion portion 33 . As shown in FIGS. 2 and 3, the rubber seal member 50 includes a tubular main body portion 51 extending in the front-rear direction and an annular protrusion 52 protruding radially inward from the front end of the main body portion 51 . Prepare. A plurality of annular lips 51a are formed on the outer peripheral surface of the body portion 51 and protrude radially outward and are arranged at intervals in the front-rear direction. A plurality of spaced-apart annular lips 51b are formed.

シール部材５０は、ハウジング３０の挿入部３３とシールドシェル４０との間に挟まれるように配置される（図２参照）。このため、まず、シール部材５０を、後側から、突部５２が環状溝部３４に進入し且つ本体部５１が挿入部３３の外周を覆うように、挿入部３３に装着する（図２参照）。この状態において、環状溝部３４に進入しているシール部材５０の突部５２は、シール部材５０の挿入部３３からの後側への脱落を防止する機能を発揮している。次いで、シールドシェル４０を、後側から、挿入部３３に外挿されるように、挿入部３３に装着する（図２参照）。シールドシェル４０の装着完了状態では、図２に示すように、シールドシェル４０に設けられた係止片４１と挿入部３３の外周に設けられた係止孔３６とが係合することで、シールドシェル４０のハウジング３０からの後側への脱落を防止する機能を果たす。 The seal member 50 is arranged so as to be sandwiched between the insertion portion 33 of the housing 30 and the shield shell 40 (see FIG. 2). For this reason, first, the seal member 50 is attached to the insertion portion 33 from the rear side so that the protrusion 52 enters the annular groove portion 34 and the body portion 51 covers the outer periphery of the insertion portion 33 (see FIG. 2). . In this state, the projection 52 of the seal member 50 that has entered the annular groove 34 functions to prevent the seal member 50 from coming off rearward from the insertion portion 33 . Next, the shield shell 40 is attached to the insertion portion 33 from the rear side so as to be externally inserted into the insertion portion 33 (see FIG. 2). When the shield shell 40 is completely attached, as shown in FIG. 2, the locking piece 41 provided on the shield shell 40 and the locking hole 36 provided on the outer periphery of the insertion portion 33 are engaged with each other, so that the shield is secured. It functions to prevent the shell 40 from falling rearward from the housing 30 .

シールドシェル４０が装着されることで、シール部材５０の本体部５１は、ハウジング３０の挿入部３３とシールドシェル４０との間に押圧挟持される。この結果、本体部５１は、挿入部３３とシールドシェル４０との間の環状隙間を封止する機能を発揮する。本体部５１が挿入部３３とシールドシェル４０との間に押圧挟持された状態では、環状リップ５１ａ，５１ｂが押し潰されている。このため、本体部５１の径方向の高さ（環状リップ５１ａの先端と環状リップ５１ｂの先端との間の距離）が、挿入部３３とシールドシェル４０との間に挟持される前の組付前高さＨ１から、組付後高さＨ２に減少している（図２参照）。 By mounting the shield shell 40 , the body portion 51 of the seal member 50 is pressed and held between the insertion portion 33 of the housing 30 and the shield shell 40 . As a result, the body portion 51 functions to seal the annular gap between the insertion portion 33 and the shield shell 40 . The annular lips 51a and 51b are crushed when the body portion 51 is pressed and held between the insertion portion 33 and the shield shell 40. As shown in FIG. Therefore, the radial height of the body portion 51 (the distance between the tip of the annular lip 51a and the tip of the annular lip 51b) is the same as the height of the assembly before the insertion portion 33 and the shield shell 40 are clamped. It is reduced from the front height H1 to the post-assembly height H2 (see FIG. 2).

次いで、ブーツ６０について説明する。ゴム製のブーツ６０は、図１に示すように、前後方向に延びる筒状の形状を有し、シールドシェル４０の外周を覆う大径部６１と、シールドシェル４０から後方に延出する一対の電線２０の外周を覆う小径部６２と、大径部６１と小径部６２とを連結する繋ぎ部６３と、を一体に備える。ブーツ６０は、一対の電線２０に挿通された状態から、一対の電線２０に対して前方へ相対移動させて、ブーツ６０の大径部６１をシールドシェル４０の外周に装着することで、シールドシェル４０及び一対の電線２０に装着される。ブーツ６０は、シールドシェル４０から後方に延出する一対の電線２０を保護する機能を果たす。 Next, the boot 60 will be explained. As shown in FIG. 1 , the rubber boot 60 has a tubular shape extending in the front-rear direction, and includes a large-diameter portion 61 that covers the outer periphery of the shield shell 40 and a pair of large-diameter portions 61 that extend rearward from the shield shell 40 . A small-diameter portion 62 that covers the outer circumference of the electric wire 20 and a connecting portion 63 that connects the large-diameter portion 61 and the small-diameter portion 62 are integrally provided. The boot 60 is moved forward relative to the pair of electric wires 20 from the state in which the pair of electric wires 20 are inserted, and the large-diameter portion 61 of the boot 60 is attached to the outer circumference of the shield shell 40, whereby the shield shell is opened. 40 and a pair of electric wires 20 are attached. The boot 60 functions to protect the pair of electric wires 20 extending rearward from the shield shell 40 .

次いで、パッキン７０について説明する。ゴム製のパッキン７０は、図１に示すように、前後方向に延びる筒状の形状を有しており、前後方向からみて、ハウジング３０の嵌合部３２の外周形状に対応して、幅方向に長い扁平な形状を有している。パッキン７０は、前側から、ハウジング３０の嵌合部３２の外周に装着される（図１参照）。コネクタ１と相手側コネクタとの嵌合により相手側コネクタの筒状の相手側嵌合部が嵌合部３２に外挿された状態において、嵌合部３２に装着されたパッキン７０は、嵌合部３２の外周面と相手側嵌合部の内周面との間で押圧挟持される。これにより、嵌合部３２と相手側嵌合部との間の隙間を封止する機能を果たす。以上、コネクタ１を構成する各部材について説明した。 Next, the packing 70 will be explained. As shown in FIG. 1, the rubber packing 70 has a tubular shape extending in the front-rear direction, and corresponds to the outer peripheral shape of the fitting portion 32 of the housing 30 when viewed from the front-rear direction. It has a long flat shape. The packing 70 is attached to the outer periphery of the fitting portion 32 of the housing 30 from the front side (see FIG. 1). In a state in which the cylindrical mating fitting portion of the mating connector is externally inserted into the fitting portion 32 by fitting the connector 1 and the mating connector, the packing 70 attached to the fitting portion 32 is It is press-held between the outer peripheral surface of the portion 32 and the inner peripheral surface of the mating fitting portion. This serves to seal the gap between the fitting portion 32 and the mating fitting portion. Each member constituting the connector 1 has been described above.

組み付けが完了したコネクタ１は、相手側コネクタと嵌合される。コネクタ１と相手側コネクタとを嵌合させるためには、相手側コネクタの筒状の相手側嵌合部が、コネクタ１の嵌合部３２に外挿される。これにより、コネクタ１は、一対の電線２０と相手側コネクタとを電気的に接続する中継コネクタとして機能し得る状態となる。 The assembled connector 1 is mated with a mating connector. In order to fit the connector 1 and the mating connector, the cylindrical mating fitting portion of the mating connector is externally inserted into the mating portion 32 of the connector 1 . As a result, the connector 1 can function as a relay connector that electrically connects the pair of electric wires 20 and the mating connector.

次いで、シール部材５０のゴム硬度及び圧縮率について述べる。上述したように、シール部材５０の本体部５１は、ハウジング３０の挿入部３３とシールドシェル４０との間に押圧挟持されることで、挿入部３３とシールドシェル４０との間の環状隙間を封止する機能を発揮する。挿入部３３とシールドシェル４０との間の環状隙間の大きさは、ハウジング３０及びシールドシェル４０の製造公差によって変化し得る。よって、シール部材５０の本体部５１は、このような製造公差による環状隙間の大きさの変化を適正に吸収し且つ環状隙間の気密性を維持可能な特性を備えることが好ましい。以下、説明の便宜上、組付前高さＨ１と組付後高さＨ２との差である潰し高さ（Ｈ１－Ｈ２）を組付前高さＨ１で除算した値を「圧縮率」と定義する。 Next, the rubber hardness and compressibility of the seal member 50 will be described. As described above, the body portion 51 of the seal member 50 is pressed and sandwiched between the insertion portion 33 of the housing 30 and the shield shell 40 to seal the annular gap between the insertion portion 33 and the shield shell 40 . function to stop. The size of the annular gap between insert 33 and shield shell 40 may vary due to manufacturing tolerances of housing 30 and shield shell 40 . Therefore, it is preferable that the body portion 51 of the seal member 50 has characteristics capable of appropriately absorbing changes in the size of the annular gap due to manufacturing tolerances and maintaining the airtightness of the annular gap. Hereinafter, for convenience of explanation, the value obtained by dividing the collapsed height (H1-H2), which is the difference between the pre-assembly height H1 and the post-assembly height H2, by the pre-assembly height H1 is defined as the "compression rate". do.

発明者による試験・考察によれば、シール部材５０のゴム硬度が３０度以上５０度以下であり、且つ、圧縮率が０．１以上０．４以下であれば、そうでない場合と比べて、シール部材５０の本体部５１が、ハウジング３０及びシールドシェル４０の製造公差による環状隙間の大きさの変化を適正に吸収可能でありながら、当該環状隙間の気密性も維持可能であることが判明した。ここで、ゴム硬度の値は、例えば、ＪＩＳ Ｋ ６２５３に定められる試験方法に準じて測定することができる。 According to tests and considerations by the inventors, if the rubber hardness of the seal member 50 is 30 degrees or more and 50 degrees or less and the compression rate is 0.1 or more and 0.4 or less, compared to the other cases, It was found that the main body portion 51 of the sealing member 50 can properly absorb changes in the size of the annular gap due to manufacturing tolerances of the housing 30 and the shield shell 40, while maintaining the airtightness of the annular gap. . Here, the value of rubber hardness can be measured according to the test method defined in JIS K 6253, for example.

具体的には、製造公差による環状隙間の大きさの変化幅が１．２ｍｍ（±０．６ｍｍ）である場合を想定し、環状隙間の気密性が５０ｋＰａ以上のときに気密性が「合格」と判定し、環状隙間の気密性が５０ｋＰａ未満のときに気密性が「不合格」と判定した。シール部材５０のゴム硬度が３０度以上５０度以下であり、且つ、圧縮率が０．１以上０．４以下であれば、環状隙間の大きさが上記変化幅の範囲内の何れの値であっても、気密性が「合格」となった。一方、シール部材５０のゴム硬度が３０度以上５０度以下ではない、又は、圧縮率が０．１以上０．４以下ではない場合、環状隙間の大きさが上記変化幅の範囲内の或る値であるときに、気密性が「不合格」となった。 Specifically, assuming that the width of change in the size of the annular gap due to manufacturing tolerances is 1.2 mm (±0.6 mm), the airtightness is "passed" when the airtightness of the annular gap is 50 kPa or more. When the airtightness of the annular gap was less than 50 kPa, the airtightness was judged to be "failed". If the rubber hardness of the seal member 50 is 30 degrees or more and 50 degrees or less and the compressibility is 0.1 or more and 0.4 or less, the size of the annular gap can be any value within the range of the change width. Even if there was, the airtightness was "passed". On the other hand, if the rubber hardness of the seal member 50 is not 30 degrees or more and 50 degrees or less, or if the compressibility is not 0.1 or more and 0.4 or less, the size of the annular gap is within the range of the change width. value, the airtightness was "failed".
